Abstract

Thermoplastic, branched, high-molecular weight polycarbonates endowed with properties of flame-resistance (self-extinguishing polycarbonates) are characterized by the presence in their polymeric chain of units deriving from a di-hydroxy-aromatic compound having the formula: <CHEM> wherein: R is a single bond; or is a substituted or non-substituted, linear or branched alkyl group containing from 1 to 5 carbon atoms; or is a group selected from O, S, SO2, CO; X and Y are equal to, or different from, each other and stay for H or CH3; m and n are integers, equal to or different from each other, ranging from 1 to 4; and of units deriving from a mono-halogenated tetra-phenyl compound having the formula: <CHEM> wherein: R, R2, R4, R6 stay for OH; R1, R3, R5, R7, either equal to, or different, from one another, stay for OH, H, or a linear or branched alkyl group of from 1 to 5 carbon atoms.
